Viable Direct Air Capture has arrived
The electrolyzer of the future.

Cheap materials. 


Intermittent operation. 


Producing CO₂ and H₂ at scale.

Brineworks’ electrolyzer is turning ultra low-cost DAC from dream to a reality. Most DAC systems rely on expensive sorbents, continuous operation, and thermal inputs. We use saltwater, intermittent electricity and zero precious metals for radically lower CAPEX and more flexible location options.
  • Step 1

    Electrolysis

    Our system produces acid and base from saline water. The base is used for CO₂, capture and release.

  • Step 2

    Air Contacting

    Air contacting with the base from our system is used to capture CO₂, into water.

  • Step 3

    Gas Production

    Acid from our system is used to liberate CO₂, from the water which we capture for storage or utilization, all while co-producing H₂.

What we're building

CAPEX

Low - abundant metals, plastics, cheap membranes

H₂

Maximized H₂ co-production (optional)

Deployability

Anywhere - designed for solar PV without batteries

Energy price/cost

Solar + wind only = low cost

  • Intermittency ready

    Intermittency ready

    We don’t store energy. We don’t need to. 
Our system turns on and off with the sun — no batteries, no added costs.

  • Cost trajectory

    Cost trajectory

    Target: <$200/ton-CO₂ by 2030

    Long-term: <$100/ton-CO₂

  • Deployment flexibility

    Deployment flexibility

    Operates wherever low-cost renewable energy is available—from sunny regions and windy coastlines to hydro-rich northern areas.
